Far-end side airbag device, using method thereof and automobile

Abstract

The invention provides a far-end side air bag device, a using method thereof and an automobile. The far-end side air bag device comprises a first inflatable air bag, a second inflatable air bag and atensioning pull belt; the first inflatable air bag is arranged at the front of a seat and abuts against the forehead of a passenger after being inflated to limit the displacement of the head of the passenger in the X direction; the second inflatable air bag is arranged on the side edge of the seat and abuts against the side face of the body of the passenger after being inflated, so that the displacement of the head of the passenger in the Y direction is limited, and the bending moment of the neck of the passenger is limited; and the tensioning pull belt is connected with and tensions the inflated first inflatable air bag and the inflated second inflatable air bag, so that the first inflatable air bag and the second inflatable air bag form an included angle of a preset angle, and the side face of the passenger is protected when the side face column of the automobile collides with something. The supporting effect of the far-end side air bag device on a dummy head is improved, and the Y-direction deviation value of the head and the bending moment damage value of the neck are reduced.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to a remote side airbag device, a use method thereof and an automobile. Background technique [0002] The far-end side airbag is usually installed on the right side of the driver's seat, and its function is to prevent the occupants of the same row from colliding with each other or the far-end occupants from colliding with the door guard / B-pillar guard on the other side when a side collision occurs, so as to Protect the occupant's head, chest and other vital parts. [0003] The evaluation of side and remote protection has been included in the 2020 version of ENCAP (European Union New Car Certification) evaluation procedures, and the remote side airbag is used as a carrier to achieve side and remote occupant protection. Currently, there are few researches on the remote side airbag suitable for pure electric vehicles in the market . [0004] Due to the harsh collision wavef...

AI Technical Summary

Problems solved by technology

[0004] Due to the harsh collision waveform of the pure electric vehicle in the column collision condition, the relative movement of the dummy head is greater, and the movement restriction and support of the dummy head by the far-end side airbag are generally insufficient, resulting in the Y-direction deviation of the head and the neck The bending moment damage value exceeds the standard, which cannot achieve the goal of vehicle safety and remote occupant side protection
